Assign CSS Class using Java Script

To assign class name on the fly is very simple, Create a DIV and give it an ID.
<div id=”myId”> This is test</div>

at the page end, write the below code.

<script>

document.getElementById(“myId”).className=”ANY_CSS_CLASS”;

</script>

TIP: While accessing element with their ID’s always specify the script at the bottom of the page so that valid object could be found, otheriwse null will be returned by the script.
